7.1 Emergency lowering in case of power failure
In case of power failure the lift can not lowered with the motors. In this case there is the
possibility to lower the lift manually. Draw the main plug or switch off and lock the
main switch and remove the cover of the v-belt pulleys. For this the lift must be turned
down to lowest position at the nut on the top end of the spindle. If the lift is in the
lowest position removes the vehicle.
The emergency lowering must only carried out by persons which are
instructed to using the lift. Please refer to the regulation “Lowering the
vehicle”.
Procedure – emergency lowering
• loose the main plug; switch off the main switch and lock it.
• remove the cover of the v-belt pulleys.
• lower the lift: turn the nuts (every side) alternately 5 cm until the lift has reached
lowest position.
• after the emergency lowering: Do not work with the lift until the faulty parts are
exchanged.
7.2 Driving onto an obstacle
If the lifting arm or the lifting carriage is driven on a obstacle, the motor from this side
locked. The lift switched off if the lifting carriage are not more in the regulation range
(approx. 25 – 30 mm) (since 9/99 64 mm).
An additional protection is a temperature control in the motor. Which interrupt the
electrical circuit when it is overloaded. You can not work with the lift. Cool down
approx. 5 – 10 min. dependently on the outside temperature.
After the locking of the motor check the V-belt if necessary replace it. Call the service-
partner.
7.3 Function of safety device
The lift is equipped with a safety switching, which controls the wear of the main nut.
If the lifting nut is broken, a safety nut which is conducted loose in the spindle, carries
the load. After a break of the nut, the lift can only once being lowered in the lowest
position. If the lift has reached the lowest position it is not possible to raise the lift.
The lifting carriage of the broken side gets mechanically locked. During the lifting the
other side is driving out of the regulation range and switched off the lift. You can not
work with the lift anymore. Call the service-partner.
If the safety device is active call the service partner!
Switch off the main switch at all repairs and disturbances!
The electrical system may only be opened by trained persons!

7.4 Manually equalisation of the carriage
The lift is equipped with a position measuring system which guarantee the
synchronisation of the lift. The electrical control recognizes if one lifting carriage is
approx. 18 mm earlier at the definite height. The electrical control stopped the motor of
this carriage until both carriage have the same height again. After it both motors are
working together again.
If the carriages of the lift are driving out of the regulation range/switching off window
of approx. 36 mm (since 9/99 64 mm), the electrical control recognizes this and
switched off the lift.
To reach the normal function of the lift you must equal manually the carriages. Remove
the cover of the V-Belt pulley at the top of the lift. Equal the lift: turn one nut until the
carriage have the same height.
7.5 Adjusting of the top limit switch and the bottom limit switch
The operating unit of the lift is equipped with potentiometer. One is for the top limit
switch and one is for the bottom limit switch. The Potentiometer may from safety
reasons being only adjusted by trained person.
Out of safety reasons: The Potentiometer only may be adjusted by competent trained
persons.
• Pull the main plug before the maintenance or repair.

It is possible if the adjustments are wrong that the lift has malfunctions. It is
danger for your life for the lift and the vehicle.
• Loose the screws of the operating unit. Pull it careful out of the column. (pic. G)
• If the Potentiometer 3 (top-limit) is turned anticlockwise, the upper end-point has
been moved up. The lift stops later.

Operating Instruction and Documentation

• If the Potentiometer 3 (top-limit) is turned clockwise, the upper end-point has been
moved down. The lift stops earlier.
• If the Potentiometer 4 (bottom-limit) is turned anticlockwise, the lower end-point has
been moved up. The lift stops earlier.
• If the Potentiometer 4 (bottom-limit) is turned clockwise, the lower end-point has
been moved down. The lift stops later.
After the adjusting do not lifting or lowering to the end position. The lift can
lock or jamming!
Alter the potentiometer easily. After it operate the lift. Repeat the process
until the normal end position is reached.
• Pay attention at the cover and the rubber behind the operating unit. Do not damaging
this parts. If the parts are faulty replace it. Otherwise the protection (IP54) against
liquids is no more ensured.
8. Installation and Initiation
8.1 Installation of the automotive lift
Regulations for the installation
• The installation of the lift is performed by trained technicians of the manufacturer or
its distribution partner. If the operator can provide trained mechanics, he can install
the lift by himself. The installation has to be done according to this regulation.
• The standard lift must not be installed in hazardous locations or washing areas.
• Before installation a sufficient foundation must be proved or constructed.
• An even installation place has to be provided. The foundations must be based in a
frost resistance depth, both outside and indoors, where you must reckon with frost.
• An electrical supply 3~/N+PE, 400 V, 50 Hz has to be provided. The supply line
must be protected with T16A (VDE0100 German regulation). The minimum
diameter amounts to 1,5 mm².
• The cable entry in the column is located in operating column topside. Another
possibility is the location of the cable entry in a boring at the base plate. However the
cable has to be secured with a cable bushing. Do not fold the cables!
8.1.1 Erection and doweling of the lift
It is necessary to dowel the lift. For this you need a concrete floor with a thickness of at
least 200 mm (150 mm with base plate) and a quality of at least B25. In case of doubt a
test boring has to be performed and a dowel is to set in. Afterwards the dowel is tighten
with a torque which is described of the dowel manufacturer (example: Liebig Company
80 Nm).
If there are defectives (cracks or hairline cracks) in the zone of influence Ø200 mm, the
foundation cannot be used to install the lift on it.
